Global Market Analysis with Focus on Swiss Regulations and Dynamic Feed-in

The year 2026 marks a turning point in the history of renewable energies, particularly in the Swiss context. While the global solar industry is technologically moving towards ultra-high efficiency and diversified storage chemistry, Switzerland is undergoing a historic regulatory system change. The full entry into force of the "Mantelerlass" (Federal Act on a Secure Electricity Supply with Renewable Energies) on 1 January 2026 ends the era of static subsidies and initiates the phase of market integration.

This blog post analyses the ten most defining trends for the year 2026. It combines the macroeconomic perspective of global technology developments with a deep exegesis of the new Swiss market mechanisms. The core of the change is the transition from a pure focus on generation to a flexibilisation of the overall system: dynamic tariffs, harmonised feed-in tariffs, local electricity communities (LEC) and the regulatory equality of vehicle batteries (V2G) are becoming the central drivers of profitability. The era of blind feed-in ends; the era of dynamic, data-driven energy management begins.

The analysis shows that investment decisions from 2026 onwards must follow a fundamentally new logic. The focus is no longer on maximising the kilowatt-hour harvest in summer, but on the chronological synchronisation of generation and consumption, as well as the provision of flexibility for the grid.

1. Global PV Technology Evolution 2026: Beyond the Silicon Frontier

1.1 The Farewell to PERC and the Rise of TOPCon and HJT

Technologically, the year 2026 will be shaped by the final market dominance of n-type cell technologies, which are replacing the previous p-type PERC cells (Passivated Emitter and Rear Cell). Global production capacity has shifted massively in favour of TOPCon (Tunnel Oxide Passivated Contact) and HJT (Heterojunction). These technologies are no longer a tune of the future, but define the standard for new installations in 2026.¹

While conventional modules have featured efficiency levels of just under 20% to 22% for over a decade, the new generation of panels is shifting commercial standards significantly into the range of 25% to 28% efficiency. This leap in efficiency is not incremental but transformative, as it drastically reduces the levelised cost of electricity (LCOE) per installed square metre of area.

Technological Differentiation:

• TOPCon: This technology has established itself as the most cost-effective successor to PERC, as existing production lines could be retrofitted with moderate effort. For 2026, TOPCon is expected to serve the lion's share of the mass market.

• Heterojunction (HJT): HJT cells offer even higher efficiencies and a better temperature coefficient, but are more demanding to manufacture. In 2026, HJT modules will dominate primarily in the premium segment and in applications where maximum performance in a limited space is required.

1.2 Implications for the Swiss Market

For the Swiss market, which is geographically and structurally characterised by limited roof spaces and comparatively high installation costs (soft costs and labour), this trend is of the highest relevance. Switzerland is not a country for huge open-space systems in the lowlands; expansion takes place on roofs, facades and infrastructures.

• Area Efficiency as a Profitability Driver: Modules with higher power density enable more yield on the same area. This is crucial because
